A polygon is any closed plane figure. It comes from the Latin poly meaning "many" and gōnia, meaning "angle." "Closed," in this context, means that the sides form a complete circuit. This definition does not exclude shapes such as an hourglass or a star where sides cross each other. When sides do not cross each other, we call them "simple polygons." For this […]

In mathematics, an equation is a statement where two mathematical expressions are equal to each other. Because this is algebra, there must be a variable in the equation. A variable is an unknown number, and we end up mostly solving these variables to prove the equation true. In some cases, we'll have to solve an equation that […]

As is usually the case in mathematics and physics, formulas and experiments usually begin with curiosity --- even if it's something profoundly simple. What caused the apple to fall from the tree? Why did the ball move faster when it rolled downhill? These simple questions evolve into more complex questions. How do we measure the acceleration of […]

Do you still remember the concept of variables and exponents? Before we jump into the topic in question, let's review. x3 x is a variable, or something that has an unknown value. The value of x may vary (hence the name). In one equation, x may be equal to 4. In another equation, x may be equal to 7 or a more complicated number like […]

Mathematics has played a major role in so many life-altering inventions and theories. But there are still some math equations that have managed to elude even the greatest minds, like Einstein and Hawkins. Other equations, however, are simply too large to compute. So for whatever reason, these puzzling problems have never been solved. But what […]

Physical quantities are used to quantify the properties of a system. To give meaning to these physical quantities, a numerical value and a unit, which is universally accepted, are combined. For example, to measure the length of a beam, we say the beam is 6 [numerical quantity] + meters [unit]. Dimensional formulas represent an essential way […]

Faced with the task of teaching your kids the geometry you learned in school, but no longer remember? Panicking because you can't remember a simple phone number anymore, let alone mathematical theories? Fell asleep during your Zoom math class? You're not alone. COVID-19 has everyone hunkered down at home, and "school teacher" has been added to our […]

To find the angle line using the y-axis, you'll need the equation of a line in reference to the vertical line. When dealing with graphs, the x- and y-axis are considered codependent. The x-axis is usually referred to as the independent variable, while the y-axis belongs to the dependent variable. Dependent Variables Let’s say you are conducting […]

A radix refers to the number of digits that are used when representing numerical figures in a positional numeral system. The maximum number of unique numbers used is called the radix. The radix can include "0." For example, the decimal system contains 10 unique digits from 0 to 9. The radix of the decimal system, therefore, is 10, or […]

"Let’s go back to the beginning." How many times have you heard this line come up in movies, novels, or even had it said to you? Most things in life usually have a beginning, a starting point, or an origin -- even math. One important principle is understanding how to find the origin of a […]
